Blaine needs a lot of things. The one thing he can't have is Kurt.

Senator Blaine AU by luthien82
This is the ongoing tale of Blaine Anderson, reigning Ohio Senator, and his PA Kurt Hummel, on whom he has a massive crush. Read about their growing friendship that evolves into something more as time goes by, seeing them through laughter, tears, hard decisions and compromise. In short: life. This series is Blaine-centric.
